How nice it would be to have a wormhole which does not drag you into the center and connects to a different universe and does not even pull you towards the sides but gives you a nice easy trip to another universe or galaxy. Would that not be really convenient?

I just saw yesterday an interesting article. https://inspirehep.net/conferences/968592 Or the PDF is here: https://s3.cern.ch/inspire-prod-files-e/ef8e5a89fc3d6bda1793928980f70abd It is authored by someone in Russia and part of a conference on the name of Alexander Friedman about Gravity. A non flat metric leads to a different kind of wormhole. Could this be a hint for the far distant future about how to transverse a wormhole?

This is his conclusion: "Now, we can see that our solution contains a traversible wormhole [5] at r = -r0 connecting two infinite space - times r > -r0 and r < -r0 • It consist of two asymptotically Lobachevskyan spaces. The scalar curvature takes different asymptotical values on these sheets. Moreover, while on the sheet with the biggest curvature we have attraction by the central source, but on the sheet with the lower curvature we have repulsion! Concluding, this solution seems to be interesting since it is spherically symmetric and free from singularity."
